[Gambas-user] Emulating wizard Back/Next navigation

[M0E Lnx]

I have to say, the array idea makes more sense to me, simply because
otherwise, it'll be hard to tell the next and back buttons which sub
to run.

I have tried an array, but object array rather than string array.

The idea is that every form that gets opened leaves a footprint in
this object array
for instance, the form's open() event would have something like this

IF ArrNav.find(me) = -1 THEN ArrNav.Add(me)

this makes reverse navigation possible by indexing the array or a
similar method. However, I am not able to work out all the bugs
resulting from this because it gets crazy when you try to move back,
then forward... then back... ends up in a crash almost every time

Can someone work out a sample I can use?
